About
I'm a third-year Ph.D. student in the department of Computer Science at Purdue University. My research interest lies in cryptography and theoretical problems using probability theory, graph theory, and combinatorics. In particular, I'm drawn to password hashing using data-independent memory-hard functions and its applications, along with quantum information theory. I've been fortunate to be advised by Prof. Jeremiah Blocki since Spring 2019. Prior to joining Purdue I completed my M.Sc in the department of Mathematical Sciences at Seoul National University and B.Sc at POSTECH.
